Change pub_tool_addrinfo.h AddrInfo and VG_(describe_addr) so as to describe
anonymous or file mmap-ed segments and shared memory segments.

* pub_tool_addrinfo.h:
    new AddrTag Addr_SegmentKind  // Client segment (mapped memory)
    new struct SegmentKind in AddrInfo

* m_addrinfo.c:
   If address is still undescribed, try to describe by findinf a client segment.

* update various tests

* mc_errors.c:
  add a call to VG_(clear_addrinfo) in MC_(pp_describe_addr)
  as the memory allocated in the local AddrInfo has to be cleared once
  info is printed.
